Patented June 20, 1933 STATES PATENT OFFICE RADIATOR SHUTTER Application filed September 15, 1932. Seral No. 633,347.

This invention relates to a radiator shutter, mainly designed for use on a tractor, the general object of the invention being to provide a set of spaced strips in front of the radiator supported in a stationary manner, and a second set of movable strips, with means for moving the set of movable strips towards and away from the rst set of strips so as to close the spaces between the strips l@ of the first set when the second set is moved toward the radiator, said second set of strips, when moved forwardly, permitting air to enter the spaces and thus flow through the radiator. l5' Another object of the invention is to provide means whereby when the movable set of strips is moved outwardly their upper ends will move before their lower parts so as to permit the air to contact the upper portion of the radiator before the lower part and then when the movable strips are moved to a greater extent, the lower portions will move outwardly so as to permit the air to contact the lower part of the radiator, the inward movement of the movable set of strips acting to close the spaces between the irst set at the lower portions thereof first after which the upper portions of the spaces are closed upon further inward movement of the movable set.

Another object of the invention is to provide means whereby the shutter can be easily and quickly put in place and removed with- 35, out the use of bolts, screws or the like entering the radiator.

Another object of the invention is to provide simple means for opening and closing the device from a point adjacent the driving seat.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying 50 drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Fig. l0 is a view partly in section of the parts shown in Fig. 9.

In these drawings, the numeral l indicates an upper bar extending across the front of the radiator A of the tractor B and the numeral 2 indicates a lower bar extending 80 across the front o f said radiator. Each bar is bent as shown to provide a plurality of V-shaped portions 3 and the ends of the bar l are shaped to form the substantially ll-shaped portions at. These U-shaped por- 85 tions extend forwardly and their free limbs are extended and fastened to the side portion of the frame of the radiator as shown at 5. rlhe ends of the bar 2 are also attached to the side parts of the frame of the radiator as shown at 6.

Strips 7 have their ends attached to the bars l and 2 with the strips contacting alternate limbs of the V-shaped parts of the bars l and 2 so that the strips are spaced 95 apart with the other limbs of the V -shaped parts extending across said spaces. Each strip 7 is formed with a diagonal major portion and a substantially straight front flange 7 and a substantially straight rear liange 7b 100 which substantially contacts the front face of the radiator.

A movable frame 8 of substantially rectangular shape has the upper ends of its side members slidably arranged in the U-shaped parts et and slotted brackets 9 are fastened to the under face of the lower member of the frame and slide on the forwardly extending brackets 10, fastened to the bottom part of the radiator frame and passing through the slots in said brackets. This frame 8 carries a plurality of vertically arranged strips 11 which are spaced apart'and are also provided with a diagonally arranged intermediate or major portion and substantially f straight front and rear flanges though the diagonally arranged part is oppositely arranged to the diagonally arranged part of the stationary strip 7 Thus when the frame 8 is moved inwardly, these strips 11 will close the spaces between thestrips 7 with their diagonal parts engaging the limbs of the V-shaped part of the cross bars which extend between the spaces left by the strips 7 with their front parts engaging the front parts 7 .of the strips 7 and their rear parts contacting the rear parts 7 of the strips 7.

The upper and lower ends of the strips 11 are bent horizontally as shown at 11 and are fastened to thev top and bottom members of the frame S.

Forwardly extending perforated lugs 12 are fastened to intermediate portions of the side members of the Iframe 8 and the horizontal part 13 of a. rearwardlyl extending bar 14; passes through the holes in the lugs 12 so that as the part 11 is moved longitudinally the horizontal part 18 will move the frame 8 andthe strips 11 carried thereby towards or away from the stationary strips 7 This part 11 passes through' the guides l5 and extends to a point adjacent the seat 16 of the tractor and has a screw threaded rear end passing through a bracket 17 attached to a part of the tractor. This bracket 17 is `formed with a recess 18 for receiving a circular fiange 19 on a nut member 20 to which a hand wheel 21 is connected, the threaded rear end of the part of the rod passing through the nut member so that by turning the wheel said rod is moved longitudinally so as to adjust the frame 8 with thestrips carried thereby towards and away from the stationary strips 7.

One end of a coiled spring 22 is fastened to the lower end of the frame 8 at that side which is opposite the side adjacent to the rod 14 and the other end of the spring is connected to a bracket 23 fastened to the frame of the radiator. This spring tends to hold the lower part of the frame 8 with the lower parts of the strips 11 engaging the strips 7 so that when the frame 8 is moved outwardly by the operating means which includes the rod 14 and its part 13, the top part of the frame 8 and the upper portions of the strips 11 will move forwardly in advance of the lower portion of the frame and the lower portions of the strips 11. Thus the lower portions of the spaces between the stationary strips 7 will remain closed while the upper portions of the spaces will be opened so that air can pass through the upper portion of the radiator while the device will prevent air from passing through the lower part thereof.

Of course after the frame 8 has been moved to a greater extent the lower portions of the spaces between the strips 7 will open so that air can pass through the entire radiator. On the closing movement of the device, the lower part will close first, due to the action of the spring 22 and then the upper portion will close. Thus with this arrangement air is admitted to the upper part of the radiator first on the opening movement so that the hot water Yin the upper part of the radiator is cooled while the colder portion of the water in the bottom part of the radiator is not affected by the air until the device is fully opened. This will prevent the bottom of the radiator from freezing and still cool the water in the upper part so that the water will remain at an even normal temperature.

From the foregoing it will be seen that I have provided a shutter composed of a plurality of spaced stationary strips and a plurality of spaced movable strips, which when moved inwardly or toward the stationary strips will close the spaces left by the stationary strips, with means whereby the operator can actuate the movable strips without leaving his seat and with means whereby the operator can regulate the opening movement as he desires and with means whereby the -upper ortion yof the device opens first and then t e lower portion opens and the closing movement being the reverse.

There are no wires or bolts running through the radiator which would cause leakageor injury to the radiator and the device can be easily and quickly attached to a tractor.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination andarrangement of the several parts provided that such change falls within the scope of the appended claims.

Having thus described my invention, what I claim as new is l. A radiator shutter comprising upper and lower bars extending across the front of the radiator and each'forrned of a plurality of V-shaped parts, strips `connected to alternate limbs of the V-shaped parts of the bars, a frame movably supported at the front of the radiator for movement towards and away therefrom, a plurality of diagonally arranged strips carried by the frame for closing the spaces between the first mentioned strips when the frame is moved rearwardly, and means for moving the frame.

2. A radiator shutter comprising, upper and lower bars extending across the front of the radiator and each formed of a plurality of V-shaped parts, strips connected to alternate limbs of the V-shaped parts of the bars, a frame movably supported at the front of the radiator for movement towards and away therefrom, a plurality of diagonally arranged strips carried by the frame for closing the spaces between the firstmentioned strips when the frame is moved rearwardly, means for moving the frame, and a spring connecting the lower part of the frame to a part and tending to hold the lower part of the frame in rearmost position.

3. A radiator shutter comprising, upper and lower bars extending across the front of the radiator and each composed of a plurality of V-shaped parts, the upper bar having forwardly extending guiding parts thereon, a plurality of strips connected with alternate limbs of the V-shaped parts and each including a diagonally arranged part, a rearwardly extending straight part and a forwardly extending straight part7 a frame having portions slidably arranged in the guiding parts of the upper bar, guiding means for the lower part of the frame, a plurality of spaced strips carried by the frame for engaging the other limbs of the V-shaped parts when the frame is moved rearwardly whereby the strips carried by the frame will close the spaces between the first-mentioned strips, each of the strips carried by the frame including a diagonally arranged intermediate part and straight edge parts contacting the straight portions of the first-mentioned strips, and means for moving the frame.

In testimony whereof I affix my signature.
